Race info & registration

Three top athletes will start in the first edition of the 265km BTX marathon in South Africa. These three athletes have won many prizes.

We are especially looking forward to see what the German Benedikt Hoffmann and the Frenchman Benoît Cori have up their sleeve, or do we have to fear another Kenian ... ?

In the women's group the focus is on Nathalie Mauclair, but Kenia will certainly do whatever it takes to keep up with her.

Of course we don't know how well prepared the rest of the athletes are for this unique race... Who knows ...

BreathTaking Adventure

Entabeni, at 22 000 hectares, is small by South African standards, but it is one with the most beautiful and varied nature. It is home to the Big 5 and now also to our races. 
You will be running among the wildlife across the savannah, through the bush, making your way along river-beds and climbing up and back down rocky plateaus. Five different ecosystems will be your race stages varying between 1500m and 2000m altitude above sea level.
Entabeni is perfect for a BreathTaking adventure.
You will use our custom-developed technology, called Green Zone, for following the race course which has no preplaced markings.
Each runner wears a display on their wrist, following a green arrow on the display’s screen. If the runner goes off course the arrow turns red, the alarm sounds, and our staff are automatically notified. Every runner is tracked at all times by the race staff using Green Zone, ensuring complete safety of all participants.
The technology is enabled with a personal alarm. Together with the highly-skilled rangers on the ground, the safety of all participants is ensured.
Entabeni means “place of the mountain”, and it is situated in the UNESCO World Heritage Waterberg Biosphere. 
Located approximately a four-hour drive north of Johannesburg, Entabeni is malaria-free and boasts five eco-systems. The higher part of the reserve, the plateau, consists of craggy rock formations and grasslands. Below the 600 metre-high rocky precipices of the plateau lies a warmer sandveld ecosystem interspersed with lush wetlands.
The reserve is home to a great diversity of wildlife, including the African Big 5 – elephants, lions, rhinos, leopard and buffalo. You can also see cheetahs, hippos, crocodiles, wildebeest, zebras and leopards and several species of antelope.
In total there are 55 mammal species, 300 plants species, 380 bird species and many reptiles and amphibians. The lion is the top predator here.

You will be running for Rhino’s and for...

A part of your entrance fee will be donated to Ntolo Ya Lerato Rhino Orphanage and The Legend African Foundation. Both are located in Entabeni and that’s another reason why we have chosen Entabeni for our races.

Ntolo Ya Lerato Rhino Orphanage was the world’s first orphanage for rhino calves whose mothers have been killed by poachers. Your help will be greatly appreciated and is badly needed - rhinos are being wiped out by poachers for their horn, and we may lose rhinos completely very soon unless drastic changes are made.

Entabeni Safari Conservancy has played a pivotal role over the last few years in many conservation projects in the region - protecting, restoring and rehabilitating the reserve area and its wildlife species and fostering sustainable, mutually beneficial relationships with local communities.

Nature conservation in Africa and prevention of rhino extinction is now inseparable from economic realities - your participation in this race shall directly contribute to the process of conservation and sustainable development of the area.
